Among the thousands of Nadis, three hold supreme importance: Ida, Pingala, and Sushumna. Together, they form the core of the subtle body system and are essential for spiritual evolution.

In the Pranamayakosha or the energy body, there are 72,000 nadis. The 72,000 nadis spring from three basic nadis—the left, the right and the central—the Ida, Pingala and Sushumna.

There are 72,000 nadis in the body with three main channels up the spine, right, left and centre. These are known as ida, pingala & sushumna.

As mentioned by the Hatha Yoga Pradipika and Goraksha Samhita, of the 72,000 nadis, Ida, Sushama and Pingla are the main that we associate with Ganesh ji's trunk.

The energy of the sun is taken in through the right nostril or surya swar controlled by the Pingla nadi. The left nostril is chandra swar and is controlled by the Ida nadi.
